fortran/use-mpi-tkr: remove old kruft

These subroutines are no longer referenced in the "mpi" module
interface; remove them.

I *believe* that these subroutines may have been kept for ABI /
backwards linking compatibility at one point.  But for Open MPI
v5.0.0, we're breaking ABI, so these old symbols do not need to be
maintained any more.
